Abstract

A conventional diplexer is made up of two channel filters which are connected to a transmission-line based signal distribution network. In this work, a novel diplexer has been proposed and designed using hairpin resonator filters that are joined together using a patch resonator. The patch being a dual-mode is made to resonate at the centre frequencies of the channel filters in corresponding modes. The patch functions as a signal splitter and at the same time as a resonant pole for each of the channel filters. A diplexer with the channel centre frequencies of 3.99 GHz and 4.39 GHz and 4% fractional bandwidth has been designed and tested. The simulated and measured results show very good agreements.
